Here is a newbie approach for this particular example.

aa = (3.4*10^62 + 4.5*10^63 x)/(6.7*10^64 + 8.9*10^63 x)

Simplify[Factor[aa[[1]] ]*Factor[aa[[2]] ] ]

So, while openness provides a couple of security advantages in itself, 
the chief reason why Linux and BSD offer superior security is not so 
much because they're open source, but because they're not Windows.
